Valtteri is also excited to try out the new upgrades and admits that in such a close fight at the front, any small gains that can be made are absolutely crucial.
"I hope it's massive, but of course we have to find out," the Finn said. "It's a decent upgrade, which is very much needed, like any small gain this year, so I'm looking forward to trying it out.
"Last weekend with the new engine, it was positive. But, now even with the engines between us and Ferrari the margins are very, very small.
"I don't feel like we really have the upper hand like Mercedes has had in past seasons with the engine. So, any small gains are important.
"The team has been good reacting to situations, if we feel like we have been on the back foot or had issues. We have been very strong in solving issues and learning through the season.
"They've been working really hard on these new upgrades. The development race is going to continue and as it is not, it's going to be really important."
